HZ1220 Volumetric And Coulometric Karl Fischer Titrator
I. Volumetric Karl Fischer Titration
The volumetric KF titration mode supports both KF Titration Mode and Titer Detection Mode, providing flexibility for different moisture determination applications. Reagent handling is fully automated with auto-filling, auto-purging, and auto-mixing functions, ensuring safe and convenient handling of Karl Fischer chemicals.
To ensure measurement accuracy, the system supports both automatic and manual background drift correction, compensating for any ambient moisture ingress. A wide range of selectable units-including mg, mg/L, %, ppm, and others-accommodates diverse reporting requirements.
Users can configure multiple parameters, including measurement unit, polarization current, stirring rate, titration rate, stop volume, endpoint potential, and stop criterion, allowing optimization for specific sample types. The instrument stores up to 200 titration data sets in full compliance with GLP standards.
II. Coulometric Karl Fischer Titration
The coulometric KF titration system features a generator cell with diaphragm for precise coulometric determination. Automatic and manual background drift correction ensures accurate and reliable results.
Selectable units include μg, mg, %, ppm, mg/L, μg/mL, and others, providing flexible data reporting options. Configurable parameters include measurement unit, polarization current, stirring rate, generator current, endpoint potential, and stop criterion, allowing users to tailor the method to their specific requirements.
The instrument stores up to 200 titration data sets, fully compliant with GLP requirements for data integrity and traceability.
